Abstract
A forwarding engine of a router device may replace addresses of some IP packets by virtual ones such to mask the active routing daemon. This is used in unicast regime when said forwarding engine forwards incoming IP packets from neighbor routers to said routing daemon. It is also used in unicast as well as in multicast regime in the opposite case. A standby routing daemon may also be used on another processor by affecting same virtual addresses for its ports as the first active routing daemon. In a case of failure of the first active routing daemon, a controller will switch said standby routing daemon to be the new active daemon connected to the forwarding engine. A CompactPCI bus can be advantageously used. In that case, the forwarding engine is a peripheral board of the controller of that CompactPCI.
